Do Panda Cory's produce venom?
It's little more than a minor irritation to human skin, but this venom can be harmful to other fish when released throughout the aquarium. For this reason, you will want to ensure that your corydoras remain happy and healthy in good quality water, and that any losses are swiftly removed from the aquarium.
Corydoras have the ability to breathe air intestinally, so a gap should be left between the water surface and the fish tank hood/lid to allow the Cory to come up to the surface and take air in. It is perfectly normal for a Corydoras to do this many times a day.
